STOVE.

4Specicaton of Letters Patent No. 22,787, dated February 1, 1859.

To all whom it may concern:

. Be it known that I, PORTER DoDeE, of Francestown, in the county of Hillsboro and State of New Hampshire, have invented an Improved Air-Tight Stove; and I do hereby declare thatthe same is fully described and represented in the following specification and the accompanying drawings, of lwhich-- Figure l denotes a side elevation of the said stove. Fig. 2, a horizontal section of it. Fig. 3, a vertical and transverse section of it. Fig'. 4f, a longitudinal, vertical and diagonal sect-ion taken through opposite corner posts.

My stove is constructed of an iron frame and stone panels, they being put together in a peculiar manner as will be hereinafter described. The iron frame is composed of a base A., which may be wholly or in part of castiron, or be formed with a cast iron rim a, (having a stone hearth b, fitted into it,) a cap rim or frame B, and vertical corner posts c, c, c, c, arranged as shown in Fig. 4L. Each of said posts has a flange d, extended from each outer edge of it as seen in Figs. l and 2. It is'also provided with a ange e, projecting inward from it as shown in Figs. 2 and 3. These flanges are intended to secure in place an inner and outer series of stone panels D, D, D, D, etc., which are arranged within them and extend upward from the bottom of the stove as shown in the drawings. Each panel or slab of stone is separate and independent from that one which is next adjacent to it. The inner row of panels may be made of steatite, fireclay, or any other suitable heat resisting stone or composition, while the outer panels may be made' of steatite or marble. By means of two sets of panels, applied in manner as described, the great heat of the fuel is received.- upon the inner series which to a great extent protects the outer series because, being separated therefrom, the inner row of panels Vcan expand suddenly with little or no danger, and without causing the outer panels or either of them to be ruptured or cracked as would be likely to occur if said outer panels were in direct contact with the fire. The inner panels are of less height than the outer ones in order that they may have a free opportunity to expand upward. In order to confine the parts of the stove together, screw rods F, F, may be extended downward through the top and bottom as shown in Figs. 2, and 4:.

The cap rim B, is formed to receive a soapstone cover G, which is placed within 1t as shown in Figs. 3 and 4. A door frame and door may be applied to one end of the stove if desirable. For the reception of the smoke or discharge pipe, the panels may be perforated at any proper part and the pipe be fixed into the aperture.

The air tight stove constructed entirely of sheet iron or metal is objectionable in many respects. The metal being thin and a good conductor of heat either injures the atmosphere surrounding it or soon becomes burned or damaged by the powerful heat to which it may be subjected. For this reason stoves construct-ed entirely of plates or slabs of steatite or soapstone have been preferred, but as usually made they have their disadvantages, their mode of construction rendering them liable, when in use, to open at their joints, so as either to emit smoke into the room or to admit too much air into the stove. Besides, if a slab becomes broken or cracked, the parts of it are liable to fall out of place. My improved stove, made in the mannerV described is not liable to such disadvantages. While it emits the pleasant heat of the soapstone, it possesses the necessary strength and arrangement of its parts for endurance of great heat.

Having described my improvement in stoves, what I claim therein as new and of my invention and desire to secure by Letters Patent, is-

An improved air tight stove, the several parts being constructed and arranged in relation to each other substantially as shown and described. Y

In testimony whereof, I have hereunto set my signature this twenty-sixth day of December A. I). 1856.
